Doppler Surrogate Endoscopy for Screening Esophageal Varices in Patients With Cirrhosis

摘要

Background:Portal hypertension is a common consequence of hepatic cirrhosis, which causes esophageal varices. Bleeding from varices has a high mortality rate. The present gold standard for diagnosing varices is endoscopy. Considering endoscopy side effects and patients' low acceptance, there have been always efforts for finding alternative diagnostic methods including Doppler ultrasonography (US).
